PLANT FORCER AND PROTECTOR.

Specification of Letters Patent.

Application filed July 6, 1915. Serial No. 38,137.

To all whom it may concern:

Be it known that I, J osnrn A. KnAN'rz, a citizen of the United States,residing at Canal Dover, in the county of Tuscarawas and State of Ohio,have invented a new and useful Plant Forcer and Protector, of which thefollowing is a specification.

My invention relates to plant forcers and protectors made up ofdetachable members.

The objects of my present invention are, first, to provide a device ofthe character described which can be knocked down for shipment orstorage, second, to provide means for easily connecting the variousmembers to produce the structure for actual use, and third, for thegrowth and the protection of plants.

These objects, together with other objects readily apparent to thoseskilled in the art, may be attained by the construction illustrated inthe accompanying drawings, although the invention may be embodied inother forms, the construction illustrated being chosen by way ofexample.

In the accompanying drawing:

Figure 1 is a perspective view showing the diflerent parts properlyassembled.

Fig. 2 is a vertical section.

Fig. 3 is a sectional view of one of the joint or connecting flanges.

Fig. 4 is a section on line 4.-4, Fig. 2.

Fig. 5 is a view showing the connecting flanges detached from eachother.

Fig. 6 is a view showing a portion of one side, the back showing partsbroken away and illustrating a portion of the top.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawing.

In the accompanying drawing, 1 represents the side members which arequadrangular in shape and are so formed for the purpose of producing astructure when the various parts are assembled which will be of suchshape that it can be placed in position to receive proper light andheat. The side members 1 are provided at their opposite ends with thefolded flanges 2, which are for the purpose of receiving the open foldedflanges 3 formed upon the back 4 and the front or narrow plate 5. Thefolded flanges 2 and 3 are so formed that they can be slidably connectedtogether and when slidably connected together are in the position shownin Fig. 3. The top inclined edges of the side members 1 are providedwith the open grooves 6, which are for the purpose of receiving andholding the glass top or cover 7. The plate 5 is arranged as shown inFig. 1 and Fig. 2 and is connected by means of the seam flanges 2 and 3.The plate 5 when properly connected to the side members 1 willconstitute a support or stop for the glass top 7 the lower edge orportion of said glass top coming in contact with the plate, this featurebeing best illustrated in Fig. 2.

For the purpose of providing ventilation, the glass top 4 should beformed somewhat shorter than the length between the plate 5 and the backplate 4, by which an air space 8 is provided.

For the purpose of strengthening and stilfening the various metal parts,the front plate or member 5 is provided with the lateral flanges 9, theside member 1 with the lateral flanges 10, and the back member with thetop and bottom flanges 11. It will be understood that by forming thejoints of open hooked flanges. said flanges can be telescopicallyconnected or the parts slid into position to connect all of the metalparts, by which arrangement the parts constituting the structure can beshipped or stored in a knock-clown condition and when desired for usecan be easily and quickly connected together to produce the structuresuch as shown in Fig. 1. It will be understood that by forming thestrenghtening flange 11 at the top of the back plate it serves a doublepurpose, to-wit, said flange will act as a guide to enter the glass topsinto the open grooves formed upon the top edges of the inclined sidemembers.

Having fully described my invention what I claim as new and desire tosecure by Letters Patent, is:

In a knock down plant forcer and protector, the combination of sidemembers having inclined top edges, said side members provided with openhooked flanges, the bottom edges of said members provided with members,said back and front plates pro vided With strengthening flanges, atransparent cover shdably mounted in the open @ogpfieo of this patentmay be obtained for five cents grooves formed in th inclined top edgesof the said members, all arranged, substantlaily as specified.

In testimony that I claim the above, I hav hereuntosubscribed my name.
